Record interchange within the registry federation. Searchable registries harvest resource descriptions from all publishing registries via a standard protocol. Some registries, like the one operated by CHiMaD, can manage records for a particular sub-community, possibly pulling in records through customized APIs. Other registries, like the one operated at NIST, can serve the at-large community where providers can create and maintain records through a GUI interface.
